This was Minsk six years ago today. Hundreds of thousands of Belarusians took to the streets for freedom on October 25, 2020. I know how hard these years have been. But we have not given up on our country. I will keep working for the day we can all live there without fear.

Invisible values are the most dangerous kind. Because no one questions them. How urban streets are discussed on social media. (📸 by @nicolasblume)

It’s true. X punishes me for my posts. The more I write, the worse my reach gets.
Elon Musk has done to x what he did to starlink. That’s why pro Ukraine posts get almost no coverage

Putin's army is stuck. Now he is trying to win through propaganda and a terrorist campaign
Replying to @TheStudyofWar
2/ Russian forces have made effectively zero net gains in 2026 at the cost of over 40,000 casualties per month since July and around 458 casualties for every square kilometer of territory that Russian forces lost.

”Hon berättar hur personen i andra änden sa ”du lägger fan inte på, jag vet var du bor, och du ska lära dig att lyda mig”. Han var arg och påstod att hon var för ”tvångsblandning”. Och så kallade han henne för landsförrädare.” Vedervärdigt dn.se/ledare/ett-kommunalrad…

The GRU hacked into Jared Kushner's iPhone. Dutch military intelligence (MIVD) then recruited a GRU spy who gave them access to the hacked phone. What MIVD discovered was that Kushner had access to two bank accounts --one Azerbaijani, the other Israeli --where Saudi Crown Prince Mohammed bin Salman and Emirati ruler Mohammed bin Zayed deposited money. It sounds like a slightly far-fetched episode of "Slow Horses," but it's real. And it proves just how eye-poppingly corrupt this administration was and continues to be as its "special envoy" decides the fate of tens of millions in Europe in the Middle East. Simply incredible reporting by Matthew Cole, drawn from his new book on Kushner. vanityfair.com/story/jared-k…

Den här lama ursäkten för ett politiskt parti fyller ingen som helst vettig funktion längre. På sin höjd kan L och @SMohamsson tjäna som sinnebilder för ynklighet, opportunism och karaktärlöshet. ”Jag har ett förtroende för Jimmie Åkesson” … herregud. expressen.se/nyheter/politik…

It all makes you wonder what Putin has on Trump It would clearly finish Trump forever
“At a time when Donald Trump’s party is struggling to hold both houses of Congress and his own approval ratings are cratering to historic lows, the President has been campaigning hard all week against . . . Volodymyr Zelensky,” Susan B. Glasser writes. “Yes, Trump’s October preëlection surprise is that he’s finally decided to begin openly helping Vladimir Putin in Russia’s war of conquest against Ukraine.” “Trump has pivoted to Putin so many times before that it should hardly astonish anyone that he did it again,” Glasser continues. “But these crises that Trump provokes with such regularity always manage to reveal something new, and this one has been no exception, showing a President so politically cornered by the consequences of his war in the Middle East that he turned to Putin to help him out with less than three weeks to go before the midterm elections.” Read her latest column: newyorkermag.visitlink.me/y7…

“The mobility transition’s biggest obstacle isn’t a lack of support, but a misunderstanding of how much support there is. We must stop blindly accepting the loudest voices and focus on what the silent majority wants: a city where the car isn’t the norm, but one of many options.“

Snyder: Unlike Czechoslovakia, Ukraine resisted. Unlike Poland in 1939, Ukraine's leadership did not leave and the resistance was effective. If Ukraine had surrendered, Russia would hold its territory, resources and technology. The conflict would be much bigger. 1/
